for our gospel did not come to you in word only, but also in power and in the Holy Spirit and with full conviction; just as you know what kind of men we proved to be among you for your sake.

but just as we have been approved by God to be entrusted with the gospel, so we speak, not as pleasing men, but God who examines our hearts.

nor did we seek glory from men, either from you or from others, even though as apostles of Christ we might have asserted our authority.

For this reason we also constantly thank God that when you received the word of God which you heard from us, you accepted it not as the word of men, but for what it really is, the word of God, which also performs its work in you who believe.

who both killed the Lord Jesus and the prophets, and drove us out. They are not pleasing to God, but hostile to all men,

and that no man transgress and defraud his brother in the matter because the Lord is the avenger in all these things, just as we also told you before and solemnly warned you.

So, he who rejects this is not rejecting man but the God who gives His Holy Spirit to you.
